Notes by: Shaul

• Review of Draft Report and next steps
  • Review action items from last week
  • Report schedule is here
  • GitHub repo for Report (for push access, send GitHub user name to Shaul; everyone can pull)
• S4 Meeting Complementarity with balloons and space
  • Chart the space landscape: Active - LiteBIRD, PICO, Bharat; Inactive - PIXIE, CORE
  • Review the essence of LiteBIRD and PICO and their science goals
  • Review the key overlap/complementarity between space + ground: large angular scales (tau, r), frequency bands (component separation). In \ell space: 'Lensing' and delensing is the overlap area. (Note: the lensing signal may be affected by foregrounds - not clear at which resolution one needs the full frequency coverage.)
    • are there specific examples for how space/ground are complementary?
